I have seen photos of a shower dispenser that is best described as a curved piece of metal with a rectangular opening that water just pours out of, much as if someone tipped a 5 gallon bucket of water on your head; it is dispensed similar to water pouring over a waterfall. What is this type of "showerhead" called and who makes them ? I would either like to purchase one or make my own, or have one made by a local welding shop. The shower stall that I am building is 5' x 5' and the ceiling varies from 9' to 12' at its highest point, so i am thinking that in addition to a conventional shower head that an open trough of some sort would suit the shower. Please help me with the nomenclature and possibly where I might be able to acquire one. Thanks.
